DynaMut2 Predict Stability

Overview

Predict the effect of a single-point amino acid mutation on protein stability and dynamics using DynaMut2. Provide a PDB ID (4-character code from RCSB PDB), chain identifier, and mutation in the format WtPosNew (e.g., V1A means Valine at position 1 mutated to Alanine). Returns the predicted change in Gibbs free energy (ddG in kcal/mol): positive = stabilizing, negative = destabilizing. The tool downloads the PDB structure from RCSB and submits it to DynaMut2 for analysis. Computation typically takes 15-30 seconds. Based on Normal Mode Analysis and graph-based signatures.
